Burner maintenance tool

Abstract

A device for cleaning a tip of a furnace burner including a support tube of axis X intended to pass through the burner and where the support tube includes a metal cable connected at one of its ends to a scraper and at the other end to a system for setting and maintaining the position of the scraper, where the scraper is articulated on the support tube between a first position aligned with the axis X in the continuation of the support tube and a second position perpendicular to the axis X, where the scraper has a chamfered part on its profile and where the support tube is connected to a rotation means for rotating the entire whole device in rotation. It can be set in place and manipulated from the rear of the burner, thereby ensuring a good level of safety for interventions, such that a rotational and/or translational movement about the tip of the burner allows the concretions to be cleaned off effectively whatever their nature (shape, hardness, etc.) and their position.

The invention claimed is: 
     
       1. Device for cleaning a tip of a furnace burner comprising a support tube of axis X intended to pass through the burner and wherein the support tube comprises a metal cable connected at an end to a scraper and at another end to a system for setting and maintaining the position of the scraper, wherein the scraper is articulated on the support tube between a first position aligned with the axis X in the continuation of the support tube and a second position perpendicular to the axis X, and wherein the scraper has a chamfered part on a profile and the support tube is connected to a means for rotating the whole device, wherein the support tube and the scraper are hollow and communicating, the support tube is open on both sides, the scraper comprises holes communicating with the inside of the scraper and arranged on one side and the support tube and the scraper are intended to have a fluid loaded with a pulverulent material passing through them. 
     
     
       2. Device according to  claim 1 , wherein the support tube is connected to a means for hammering along the axis X. 
     
     
       3. Device according to  claim 1 , wherein the support tube and the scraper have a diameter ≤73 mm. 
     
     
       4. Device according to  claim 1 , wherein the scraper is removable and interchangeable. 
     
     
       5. Device according to  claim 1 , wherein the support tube is removable and interchangeable. 
     
     
       6. Device according to  claim 1 , wherein the support tube and the scraper are hollow and communicating, wherein the support tube is open on both sides, wherein the scraper comprises holes communicating with the inside of the scraper and arranged on one side, and wherein the support tube and the scraper are intended to have compressed air passing through them. 
     
     
       7. Device according to  claim 1 , wherein the means for rotating the whole device is a motorized wheel. 
     
     
       8. Method for cleaning a burner of a rotary furnace, comprising:
 inserting and placing the device according to  claim 1  in the burner, 
 setting the scraper in position from the aligned first position to the perpendicular second position using the position setting and maintaining system, 
 maintaining the scraper using the position setting and maintaining system, 
 rotating the device using the rotating means. 
 
     
     
       9. Cleaning method according to  claim 8 , wherein the insertion and placement of the device is performed using an actuator. 
     
     
       10. Cleaning method according to  claim 8 , wherein the device is moved in translation along the axis X manually or using a motorized actuator. 
     
     
       11. Cleaning method according to  claim 8 , wherein the metal cable is connected at the other of its ends to a motorized winch.
